Whats AMS?
Altitude sickness is caused by reduced levels of oxygen in the blood due to the lower atmospheric pressure at altitude. Early symptoms include headaches, tiredness, irritability and nausea. The high altitude will be the biggest challenge to us on this hike and can be felt from around 2500m upwards. If anyone experiences more serious symptoms they will be guided down. Not everyone is affected by altitude sickness, and fitness, size, age or sex does not make one more or less susceptible to it.
